A.
Harvard spectral classification of stars
chosen
The Harvard spectral classification of stars is an early 20th-century system that categorizes stars by their spectral characteristics and surface temperatures into types O, B, A, F, G, K, and M, forming the basis of modern stellar classification.
-
B.
Hubble sequence
The Hubble sequence is a morphological classification scheme that organizes galaxies into categories such as ellipticals, spirals, and irregulars based on their visual appearance.
-
C.
Hertzsprung–Russell diagram
The Hertzsprung–Russell diagram is a fundamental astronomical chart that plots stars’ luminosities against their temperatures or spectral types, revealing key patterns of stellar evolution and classification.
-
D.
On the Relations between the Spectra and Other Characteristics of the Stars
"On the Relations between the Spectra and Other Characteristics of the Stars" is a landmark 1914 paper by Henry Norris Russell that helped establish the relationship between stellar spectral type, luminosity, and other properties, laying groundwork for the Hertzsprung–Russell diagram and modern stellar astrophysics.
-
E.
Salpeter
Salpeter is a surname most notably associated with astrophysicist Edwin E. Salpeter, known for his pioneering work on stellar evolution and the initial mass function of stars.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
